Olympus OM-2 - Manual (Page 85)

PHOTOTECHNICAL GROUP
As a leading manufacturer of optical instruments
in various fields of modern life, OLYMPUS pro-
vided the OM System with a wide variety of Photo-
technical units, many of which can be used to
successfully document your valuable achievements
in photographs. This group includes a microscope
adapter for use with an operation microscope, an
astroscope adapter to explore the mysteries of
space and stars in conjunction with a telescope,
etc., mostly capable of attaching on the OM body.
Other outstanding advantages of this group are
the Recordata Backs 3 and 2 that are interchange-
able with the OM standard camera back. Once in
place, the No. 3 Back automatically records the
date (year-month-day) or the time (day-hour-
minute) in the lower right hand section of your
picture (camera held in the horizontal position)
simultaneously with the shutter release.
Externally, data can be displayed on the liquid
crystal panel. Meanwhile, the No. 2 Back imprints
numerical and alphabetical symbols in 4-dial
coding on the picture when the exposure is made,
of great convenience in documentation, informa-
tion filing, instant picture classification, etc. Both
Backs can be used for high speed motor drive pho-
tography and flash photography.
For Olympus Pen F and FT enthusiasts, a mount
adapter is also available for connection of these
cameras to the OM System interchangeable lenses
and other unit
